rear

Hey, thinking about putting a slightly smaller rear sprocket on at one time. I know Formula390 knows this stuff inside and out. Iknow there will be slightly less acceleration, slightly greater fuel economy, and slightly less revs at the same speed. What are the quantitative measurements on...

From the ninja 400 forums, user C Dolan: The vibration issue and the more upright riding position would have me favor the Kaw, especially if I was riding more than 100 miles nonstop. Both handle well, but the KTM rear rim is way too narrow for its 150 rear tire. Slid the ass end a lot...

So I was cleaning my chain today and ask went well until at the end when I decided to turn my bike on while it was on the rear stand. I had it in first gear with the clutch pulled all the way, and then I notice the rear wheel is spinning. I adjust my lever all the way out so I'm pulling the...

This is my first post I suppose, so hello. I live outside St. Louis, Missouri. I thought for sure I had an account when I first bought the bike a few years ago, but couldn't seem to figure out my info. Anyways, I need to replace my front and rear brake pads. The bike is not currently with me...

What spring rate i need for rc cup wp rear shock if i weigh with gear and helmet 67-68 kg. Thanks.

272.7 lbs with 2/3 of a tank of gas -at least that is what the math said after I subtracted the weight of the board the bike was sitting on. I’m not bragging and my goal was not go to great lengths to try to lighten the bike. This was merely a labor of love of tinkering and aesthetics. This is...

Anyone having any issues with the front of the bike outweighing the rear so much? right now i have 170 front to 150 rear. the 20lb different seems a lot to me. the back end does bounce around a LOT. Just curious what everyone else is at? any recommendations? etc! Note required to be at 320lbs...
